chore: remove unused dependencies

[hyperz111]

We have some unused dependencies:

• crypto-js
• js-base64

[greptile-apps]

Greptile Summary

Removed two unused dependencies (crypto-js and js-base64) from the project. Verified through codebase search that neither dependency is imported or used anywhere - the project uses native browser APIs (atob/btoa) instead of js-base64, and has no cryptographic functionality requiring crypto-js. This cleanup reduces bundle size and removes unnecessary dependencies.

Confidence Score: 5/5

• Safe to merge - straightforward dependency cleanup with no risk
• Both dependencies are verified unused through comprehensive codebase search. No imports, no usage patterns found. Lock file properly updated. This is a pure cleanup change with zero functional impact.
• No files require special attention

Important Files Changed

Filename	Overview
package.json	Removed crypto-js and js-base64 dependencies which are not imported or used anywhere in the codebase
package-lock.json	Lockfile automatically updated to reflect removed dependencies
